I'd be interested in seeing your results and final analysis for begemot. I tried (briefly) getting it to run and gave up. Post 'em! Starting with the simplest possibility -- if you run "sh filename", all you need are read permissions on the file. If you run "filename" with the #!/bin/sh in the first line, the filename itself needs to have execute permissions enabled. Try chmod a+x filename and see if that helps. If that's not the issue, then more detail on the error message would be good. There are tons of different messages and if you don't get the exact right one when you're trying to debug, you can go down lots of wild rat holes... - Chris
